Zhoudshu's Blog How to config and query Impala SQL interface of CDH with kerberos mechanism
The Problem

One is the kerberos mechanism, the other is ldap method which provided user and password.

This blog provides the configuration steps and queries demo for using ldap to impala databases.
The test environment
- CDH version 5.8.0+
- kerberos software

- Linux 2.6.32-573.el6 ...
